ABB 500PSM03 1MRB150038R0001 Rack Power Module

Product Description

500PSM03, part number 1MRB150038R0001, is a plug-in power supply module dedicated for ABB RTU560 remote terminal unit subrack. It supplies multiple regulated stable voltages for internal communication boards and I/O modules of RTU560. It supports parallel redundant configuration; two modules can work in hot standby mode, so the RTU keeps running if one unit fails. It integrates overvoltage, overcurrent and short-circuit protection, with Power OK LED status indicator and alarm signal output to the communication unit upon fault. It is an essential power component for substation automation RTU560 systems, commonly used as spare replacement for power telecontrol cabinets.
